Wiley Rein LLP

Wiley Rein LLP acts in high-stakes commercial disputes, often centered around contract and business tort claims, brand and IP litigation, and consumer protection class actions. The Washington DC-based practice is led by Ralph Caccia, who defends consumer protection and regulatory enforcement matters, including investigations and parallel civil proceedings, and Stephen Obermeier, who handles antitrust and competition disputes, APA litigation, and telecom/media-related contentious work. They are supported by Attison Barnes, who is active across commercial, government contracting, and IP litigation and arbitration, and Enbar Toledano, who concentrates on regulatory and public law disputes, including administrative challenges. Another key contact is Frank Scaduto, who handles bet-the-company disputes. Joshua Simmons departed the firm in March 2025. All practitioners are based in DC.
